Voice over: "We have the technology; we can can make you swim faster and make you remember your lap count." Background music: the theme to the Six Million Dollar Man TV show circa 1976.
This is an old story from almost two-and-a-half years ago but keep it on your radar since the technology is not only here but it is cheaper to produce.
Katie Williams was an engineering student at London's Brunel University; (AWESOME engineering and design department), and she created these kick-ass goggles, or more of a British way of saying it, has created a pair of "smart goggles" for swimmers that log lengths and time. They do so by the using the gravity created, or the spinning motion of your flip turns as the benchmark for when a lap is completed
These goggles would be so illegal at a meet but maybe they shouldn't be. They have no hydrodynamic effect like suits and they allow you to push yourself or maintain a pace. [CNN link] [Way Odd link]
